Description
The 116DEXSTC-FJ AdaptaBeacon is an in-rush current lim-
ited strobe light. When pendant, wall or ceiling mounted,
it is UL1971 Listed Signaling Appliance for the Hearing
Impaired. Stanchion mount models are UL 1638 Listed
for Private Mode Emergency Signaling. All models are
CSFM Listed.
The strobe is intended for indoor use in UL listed
compatiable fire alarm systems and other applications re-
quiring electrical supervision of signaling circuit field wir-
ing. This strobe flashes a 360-degree beam of light ap-
proximately 65 times per minute with a UL 1971 60 cd
wall and ceiling light output per Figure 7.
When assembled in accordance with these instructions,
the 116DEXSTC-FJ visual strobe signal is UL Listed for use
in Class I, Division 1, Groups C and D, Class I, Division 2,
Groups A, B, C and D, Class II Division 1, Group E, F and G,
Class II, Division 2, Group F and G, and Class III Division 1
and 2 hazardous locations with Operating Temperature
Codes per the following chart. See Table 1 for Electrical
Specifications.
This strobe is UL and cUL Listed as a Type 3R and 4X enclo-
sure. See Figure 1.

Installation
Install this unit in accordance with the applicable require-
ments in the latest edition of the National Fire Alarm Code
(NFPA 72), National Electrical Code (NFPA 70), and Cana-
dian Electrical Code.
a. Pendant Mount Models (Figure 2): Install the
catalog number 116EX-P, pendant mounting
module, to the main housing. Install explosion-
proof hanger box (not supplied). Secure 3/4" (19
mm) NPT threaded conduit (not supplied) to the
box. Install the unit on the conduit. Proceed to
step 2.
b. Ceiling Mount Models (Figure 3): Mount the
catalog number 116EX-C, ceiling/wall mounting
module, using appropriate hardware (not supplied)
suitable for the mounting surface. Proceed to step
2.
c. Bracket Mount Models (Figure 4): Install the
catalog number 116EX-C ceiling/wall mouting
module using appropriate hardware (not supplied)
for the mounting surface. Install the catalog
number 116EX-B wall mounting elbow to the wall
box. Run the unit's wiring through the elbow to
the wall box. Proceed to step 2.
d. Stanchion Mount Models (Figure 5): Install the
catalog number 116EX-S, stanchion mounting
module, to the main housing. Run the unit's wires
through the 1 1/4" conduit to the appropriate
junction box. Install the unit on the conduit.
Proceed to step 2.
2. Connect field earth ground wire to ground screw or
earth ground via conduit system.
3. Wire the unit in accordance with Figure 6. See Table
3 for required supply wire temperature ratings.
4. As appropriate, install the fixture on the mounting
module.
WARNING
To reduce the risks of ignition of hazardous atmo-
spheres and shock, do not apply power to the unit
until installation has been completed and unit is
tightly assembled and secured.
1. Mount using the following applicable method.
5. Apply power to the unit and ensure proper function.
WARNING
To reduce the risk of ignition of hazardous atmo-
spheres and shock, keep assembly tightly closed
when circuits are energized.

Maintenance
Disassemble the unit as follows (Figure 8):
2. Loosen the globe and ring assembly set screw. Insert
a suitable tool into the notches in the globe and ring
assembly and loosen the assembly by prying in a
counterclockwise direction. Remove the ring and
globe assembly.
3. Refer to Table 2 for the correct replacement catalog
number and replace the necessary part.
4. To replace, simply screw the unit on until it seats firmly
onto its gasket. Tighten the unit another 1/8 to 1/4
turn. Tighten the setscrew.
5. Reinstall the guard, where applicable, and secure using
the three supplied screws.
6. After the unit is assembled, apply power and make
sure the unit functions properly.
1. Loosen the (3) guard screws and remove the guard.
WARNING
To reduce the risk of ignition of hazardous atmo-
spheres and shock, keep assembly tightly closed
when circuits are energized.
To reduce the risk of ignition of hazardous atmo-
spheres and shock, disconnect from the supply and
circuit and allow five (5) minutes for stored energy to
dissipate before disassembling the unit.
